Radar-Integrated Front and Rear Light Set for Total Road Visibility
The Lezyne Radar React System pairs the React Drive front light with the Radar Drive rear light into a custom-programmed wireless unit built around real-time vehicle detection. The Radar Drive detects rear-approaching vehicles from up to 150 meters away and instantly communicates with the React Drive, triggering rear-facing LED indicators and audible alerts directly on the front light—no smartphone, GPS computer, or third-party device required after initial setup. The result is a self-contained safety system that keeps riders aware of closing traffic without adding anything to their cockpit.
Out front, the React Drive delivers up to 1,200 lumens for powerful night riding alongside disruptive daytime flash patterns that cut through ambient light. Both lights are IPX7 waterproof, USB-C rechargeable, and built with Lezyne's precision-engineered optics and in-house manufacturing standards. For riders who want more control, the Radar Ally app allows full customization of alert settings, light modes, and firmware updates, and the system also connects to compatible GPS bike computers.
